[0024] In order to enable those skilled in the art to better understand the technical solution of the present application, the technical solution of the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0025] like Figure 1 As shown, the present application provides a truck comprising a cab 20, a cargo box 30, and an additional drag-reducing component 10. The additional drag-reducing component 10 is mounted to the truck's B-pillar 21. Specifically, the B-pillar 21 is located behind a door 22 of the cab 20. The cargo box 30 is wider than the cab 20. Specifically, the truck can be a light truck or a heavy truck.
[0026] like Figure 2 As shown, the additional drag reduction component 10 has a guide surface X. When installed, the guide surface X is located on the side of the B-pillar 21 away from the truck's longitudinal centerline. The front side of the guide surface X is adjacent to the truck's door 22, and the rear side of the guide surface X is adjacent to the truck's cargo bed 30. The guide surface X gradually tilts away from the truck's longitudinal centerline from front to back. Specifically, for the additional drag reduction component 10 installed on the left B-pillar 21, when installed, its guide surface X is located on the left side of the left B-pillar 21 and gradually tilts to the left from front to back. For the additional drag reduction component 10 installed on the right B-pillar 21, when installed, its guide surface X is located on the right side of the right B-pillar 21 and gradually tilts to the right from front to back.
[0027] The truck provided in the present application has better carrying performance because the width of the cargo box 30 is greater than the width of the cab 20. Since an additional drag-reducing component 10 is provided, and the guide surface X of the additional drag-reducing component 10 is located on the side of the B-pillar 21 away from the longitudinal center of the truck, and gradually tilts from front to back in a direction away from the longitudinal center line of the truck, the wind flows along the guide surface X of the additional drag-reducing component 10 during operation, thereby alleviating the increase in operating wind resistance caused by the width of the cargo box 30 being greater than the width of the cab 20. Therefore, the operating wind resistance is small and the endurance performance is better.
[0028] In some embodiments, when installed, the front side of the air guide surface X is flush with the rear side of the side of the truck door 22 that is away from the longitudinal centerline of the truck. Specifically, for the additional drag reduction component 10 installed on the left B-pillar 21, when installed, the front side of its air guide surface X is flush with the rear side of the left side of the left door 22; for the additional drag reduction component 10 installed on the right B-pillar 21, when installed, the front side of its air guide surface X is flush with the rear side of the right side of the right door 22. This further helps reduce wind resistance during operation.
[0029] In some embodiments, the additional drag-reducing component 10 is provided with a shaped portion that aligns with the shaped portion of the truck's door 22. When installed, the shaped portion aligns with the shaped portion of the truck's door 22, forming a monolithic shaped structure extending from the door 22 to the additional drag-reducing component 10. Specifically, in the illustrated embodiment, a first shaped surface difference (indicated by A in the figure) and a second shaped surface difference (indicated by B in the figure) are formed on the door 22. A third shaped surface difference (indicated by C in the figure) is formed between the upper and middle sections of the guide surface X of the additional drag-reducing component 10, and a fourth shaped surface difference (indicated by D in the figure) is formed between the middle and lower sections. The front end of the third shaped surface difference is aligned with the rear end of the first shaped surface difference, and the front end of the fourth shaped surface difference is aligned with the rear end of the second shaped surface difference.
[0030] In some embodiments, when installed, the rear side of the guide surface X is flush with the side of the truck's cargo box 30 that is away from the truck's longitudinal centerline, which further helps reduce wind resistance during operation. Alternatively, the rear side of the guide surface X can be closer to or farther away from the truck's longitudinal centerline than the side of the cargo box 30 that is away from the truck's longitudinal centerline.
[0031] In some embodiments, the additional drag-reducing component 10 includes a main body 11 and a connecting portion 12. In the installed state, the main body 11 covers the protruding portion of the lower portion of the truck's B-pillar, and the connecting portion 12 is welded and fixed to the rear side of the lower portion of the B-pillar. Specifically, the B-pillar 21 includes an upper B-pillar and a lower B-pillar located below the upper B-pillar. The side of the lower B-pillar away from the longitudinal centerline of the truck protrudes in a direction away from the longitudinal centerline of the truck, protruding from the side of the upper B-pillar away from the longitudinal centerline of the truck to form a protruding portion. The main body 11 covers the protruding portion of the lower portion of the truck's B-pillar, and the connecting portion 12 is welded and fixed to the rear side of the lower portion of the B-pillar. This installation method is stable and secure, and when the vehicle door 22 is opened, there is no obvious interface on the front side of the B-pillar 21.
[0032] Specifically, in the illustrated embodiment, the main body 11 includes a cover plate 111, a front side plate 112, and a rear side plate 113. The side surface of the cover plate 111 away from the longitudinal centerline of the truck forms the guide surface X. In the installed state, the cover plate 111 is located on the side of the protruding portion of the lower portion of the B-pillar away from the longitudinal centerline of the truck, the front side plate 112 is located in front of the protruding portion of the lower portion of the B-pillar, and the rear side plate 113 is located behind the protruding portion of the lower portion of the B-pillar. More specifically, the distance between the front side plate 112 and the rear side plate 113 can be slightly smaller than the thickness of the protruding portion of the lower portion of the B-pillar, so that the front side plate 112 and the rear side plate 113 can cooperate to clamp the protruding component of the lower portion of the B-pillar.
[0033] More specifically, in the illustrated embodiment, the upper and lower ends of the cover plate 111 are bent relative to the middle portion toward the longitudinal centerline of the truck, which is more conducive to improving the installation stability of the additional drag reduction component.
[0034] Specifically, in the illustrated embodiment, the connecting portion 12 includes a plurality of mounting plates 121, three of which are shown in the figure, but in actual implementation, two or more mounting plates 121 may be provided. Each mounting plate 121 is connected to a side of the rear side plate 113 near the longitudinal centerline of the truck and is spaced apart from top to bottom.
[0035] More specifically, in the illustrated embodiment, a plurality of lugs 114 are spaced apart from top to bottom on one side of the rear side panel 113, near the longitudinal centerline of the truck. Each lug 114 is connected to a corresponding mounting plate 121. Mounting plates 121 are provided with connection holes Y, and mounting plates 121 are connected to lugs 114 via fasteners that pass through connection holes Y and the lug holes of lugs 114. This design allows the mounting plate 121 to be rotated relative to the body 11 to fine-tune its angle when the body 11 is positioned over the protruding portion of the lower B-pillar, allowing it to be welded to the appropriate position on the lower B-pillar.
[0036] More specifically, in the illustrated embodiment, the mounting plate 121 includes a first mounting plate portion 121a and a second mounting plate portion 121b. The connection hole Y is provided on the first mounting plate portion 121a. In the installed state, the second mounting plate portion 121b is welded to the rear side of the lower portion of the B-pillar of the truck.
[0037] More specifically, in the illustrated embodiment, the area of the second mounting plate portion 121 b is larger than the area of the first mounting plate portion 121 a , thereby ensuring the welding stability between the mounting plate 121 and the rear side of the lower portion of the B-pillar.
[0038] The principles and implementation methods of the present application have been described above using specific examples. The description of the above embodiments is only intended to help understand the method and core concept of the present application. It should be noted that for those skilled in the art, without departing from the principles of the present application, various improvements and modifications may be made to the present application, and such improvements and modifications also fall within the scope of protection of the present application.
